starts with provided naics (or naics based on provided title) rather than
only exact matches. Many facilities have only a longer more specific NAICS code
listed in the FRS, such as a 6-digit code, so if the category (e.g., 4-digit)
is queried then children = TRUE has to be specified to find all the sites
within that overall category.</p></dd>
